This invention relates to a hydrocarbon burner and heater, the generalobject of the invention being to provide means whereby liquid fuel andair are heated by the burner and introduced vinto a manifold from whichthe mixture is introduced by a nozzle into the burner, with means formixing air with the mixture of fuel and preheated air as it enters theburner, so that the mixture will be highly combustible and thus akheater and burner of great efficiency is obtained.`

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to

be hereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing theinvention in detail, reference will be had to theaccompanying drawings wherein like characters denote like or'corresponding parts throughout the several views, and in which Figure 1is an elevation with the housing for the burner and its coils insection.

Figure 2 is a plan view of the invention,V with parts in section.

Figure 3 is a section on line 3 3 of Figure 2.

In these views, the numeral 1 indicates a balancing reservoir into whichoil'or the like is pumped through the pipe 2 which contains the valve 3.This reservoir is fastened to a supporting member by the Vbrackets 4 anda burner 5 is supported from the reservoir by the brackets 6. A manifold7 is supported from the reservoir by the brackets 8 and a nozzle 9 isconnected with the front of the manifold and extends into a rearwardlyflaring part l() connected with the rear end of the burner, the nozzlebeing connected with said part l0 by the strips 11, so that air canenter the burner between the nozzle and the part 10 so as to mix withthe combustible mixture passing from the nozzle and more air can enterthe rear of the burner through the arcshaped slots 12 therein.

Tubes 13 are connected with the top of the reservoir -and oneA of thesetubes is coiled' around the front part of the burner, as shown 0 at 14,and the other tube iscoiled around the ies. 4serial iva-148km,

rear vpart of theburner, as shown at 15, and after being sovcoiled, thetubes are carried rearwardly, as shown at 16,V to the ends of themanifold, where they areconnected with the nozzle members 17 which'arearranged in the manifold and have their nozzle extremities curvingforwardly at approximately an angle of 45 towardtheznozzle 9, as. shownat 18, so as to force the vapor into the nozzle 9. A pipe 19 leads froma source of compressed air and is coiled in longitudinally extendingconvolutions about the burner, as shown at 20, and then thelpipe isextended rearwardly, as shown at21, where it is connected with'thecoupling 22 which in turnis connected withthe valve casing 23I and thesaid casing is connected by a pipe 24 with a nozzle 25 in the manifold,the extremity of this nozzle 25 being arranged between the nozzleextremities 18 of the fuel pipes.

A housing 26, preferably composed of copper and asbestos, surrounds theburner and the coils so as to confine the heat from the burner aroundthe coils. Thus the air and oil in the coils are highly heated from theheat from the burner and also by the heat escaping through the staggeredholes 27 in the burner and the preheated air and oil are mixed in themanifold, which acts as a balancing medium and this combustible mixtureescapes through the nozzle 9 into the burner, where it is ignited. Asthe mixture flows into the burner, it draws atmospheric air through theslots 12 and the space around the nozzle 9 and the member 10 so that themixture has great combustible qualities as the oil is vaporized lbypassing through the coils 14 and 15. By increasing the air supply, thetemperature is increased to a high degree which automatically convertsthe burner into a blow torch or heater and the combination of the oilbalancing reservoir 1, the two spirally wound oil coils 14 and 15, theair coils 20, the housing enclosing the coils and burner and the mixingand reserve manifold, produces a burner of the greatest efficiency. Thearrangement of the nozzles, 18 and 25 produces a proper mixture of theair and oil vapor and directs the mixture through the nozzle 9 into theburner.

It is thought from the foregoing descrip- 100,

tion that the advantages and novel features of the invention will bereadily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claim.

What I claim is A device of the class described comprising a reservoir,means for introducing liquid fuel under pressure into the same, aburner7 two sets of coils extending around the burner, means forconnecting one end of each coil to the reservoir, a manifold, nozzlemembers passing through the ends of the manifold and having their innerends shaped to provide forwardly curved nozzles, means for connectingthe other end of each coil to said nozzle members, longitudinallyextending coils arranged around the burner, means for conne'cting oneend of said last mentioned coil to a supply of compressed air, a nozzlein the manifold and extending forwardly7 from the rear thereof with itsoutlet and arranged between :the Curved nozzles, means for connectingthe air coils with said nozzle, an outlet nozzle yconnected with themanifold'and arranged to receive the fuel and air from the nozzles inthe manifold, said outlet nozzle being arranged inthe burner and spacedfrom the rear vpart thereof whereby air can enter the burner through thespace between the outlet nozzle and the rear part of the burner andslots 'in'the rear'part of 'the burner for the admissionof air and ahousing surrounding the burner and the coils.

Inte'stimony whereof I afiX my signature. FREDERICK C. HOHENSTEIN.
